Even if you don't know how to use a gun; even if you are afraid of guns; even if you are nervous having a gun in your home - you need to buy a gun. An armed society, using vigilance, and able to defend THEMSELVES, is the only deterrent to a government (a small number of ruling elite) that gets the grand idea that they may know more than you what's best for you, and want to force you to abide by their vision for your life.
And who knows, learning to use a gun safely and effectively may someday save your life. Don't discount this advice, it clearly was intentional that the founders wrote this into the Constitution. And it was so important, that it was written in second only to freedom of speech. Take their wisdom as a gift!
